General Description  
The TS2208A/B series are over-charge/discharge protection ICs for rechargeable one-cell Lithium-ion batteries. They  
bear an over-charge/over-discharge threshold for the battery cell voltage during charging/discharging process, and also  
provide on-time protection when excess current or short circuit occurs.  
The TS2208A/B series are essentially composed of a reference unit and three voltage detectors. During charging  
process, when the cell voltage/VDD crosses the over-charge threshold voltage VC1, the over charge detector (COM1) will  
switch the output pin (COUT) to a low level within a delay time (tC1), and thus turning off the MOSFET connected to the  
charging path. The COUT pin may change to high level again when the VDD voltage falls below “VC1-VHYS”, or when VDD  
falls below VC1 while the charger is disconnected from the battery pack.  
During the discharging process, when the VDD voltage crosses the over-discharge threshold voltage (VD1), the  
over-discharge detector (COM2) will switch DOUT to low level within a delay time (tD1), and thus turning off the MOSFET  
connecting the discharging path. In the mean time, the TS2208A/B series will enter a low current standby mode. Once  
into standby mode, it can only be released from standby after the battery pack is connected to a charger.  
The conditions of excess current and short circuit protection are both determined according to the voltage at the V- pin.  
As the voltage of V- pin reaches a greater value than VOC, which means an undesirable large current is flowing through  
the path, DOUT will be switched to a low level and the path is cutoff after internally pre-set delay time (tOC) elapses. In the  
case of short circuit, i.e. V- rises above VSHORT, the path will also be cutoff but with almost no delay time. Once the excess  
current or short circuit fault is removed, the built-in resistor at the V- pin, typically 100kohm, will pull V- down to VSS and  
bringing the IC back to normal operation.  
Together with the application circuit, the TS2208A/B will function as a consummate protector for Li-ion battery packs  
which leads to safety and long lifetime.
